OD(1) GNU textutils 2.0 (August 1999) OD(1)
NAME
od - dump files in octal and other formats
SYNOPSIS
od [OPTION]... [FILE]...
od--traditional [FILE] [[+]OFFSET [[+]LABEL]]
DESCRIPTION
Write an unambiguous representation, octal bytes by default,
of FILE to standard output. With no FILE, or when FILE is
-, read standard input.
-A, --address-radix=RADIX
decide how file offsets are printed
-j, --skip-bytes=BYTES
skip BYTES input bytes first on each file
-N, --read-bytes=BYTES
limit dump to BYTES input bytes per file
-s, --strings[=BYTES]
output strings of at least BYTES graphic chars
-t, --format=TYPE
select output format or formats
-v, --output-duplicates
do not use * to mark line suppression
-w, --width[=BYTES]
output BYTES bytes per output line
--traditional
accept arguments in pre-POSIX form
--help
display this help and exit
--version
output version information and exit
Pre-POSIX format specifications may be intermixed, they
accumulate:
-a same as -t a, select named characters
-b same as -t oC, select octal bytes
-c same as -t c, select ASCII characters or backslash
escapes
-d same as -t u2, select unsigned decimal shorts

OD(1) GNU textutils 2.0 (August 1999) OD(1)-f same as -t fF, select floats
-h same as -t x2, select hexadecimal shorts
-i same as -t d2, select decimal shorts
-l same as -t d4, select decimal longs
-o same as -t o2, select octal shorts
-x same as -t x2, select hexadecimal shorts
For older syntax (second call format), OFFSET means -j
OFFSET. LABEL is the pseudo-address at first byte printed,
incremented when dump is progressing. For OFFSET and LABEL,
a 0x or 0X prefix indicates hexadecimal, suffixes maybe .
for octal and b multiply by 512.
TYPE is made up of one or more of these specifications:
a named character
c ASCII character or backslash escape
d[SIZE]
signed decimal, SIZE bytes per integer
f[SIZE]
floating point, SIZE bytes per integer
o[SIZE]
octal, SIZE bytes per integer
u[SIZE]
unsigned decimal, SIZE bytes per integer
x[SIZE]
hexadecimal, SIZE bytes per integer
SIZE is a number. For TYPE in doux, SIZE may also be C for
sizeof(char), S for sizeof(short), I for sizeof(int) or L
for sizeof(long). If TYPE is f, SIZE may also be F for
sizeof(float), D for sizeof(double) or L for sizeof(long
double).
RADIX is d for decimal, o for octal, x for hexadecimal or n
for none. BYTES is hexadecimal with 0x or 0X prefix, it is
multiplied by 512 with b suffix, by 1024 with k and by
1048576 with m. Adding a z suffix to any type adds a
display of printable characters to the end of each line of
output. -s without a number implies 3. -w without a number
implies 32. By default, od uses -A o -t d2 -w 16.
